BAWR Reporting Sites and Target Population

BAWR Reporting Organizations are owned by the DOE-operated facilities with current employees who:

  • Have been exposed, or have had the potential for exposure, to airborne concentrations of beryllium due to their work at the present or a previous DOE site;
  • Self-identify and indicate a history of possible exposure; or
  • Exhibit symptoms of beryllium exposure, or are receiving medical removal protection benefits.

The site’s CBDPP may also include other employees in the BAWR reporting for their site, as appropriate. Subcontractors who are not included under the main site’s CBDPP must have their own CBDPP and report data separately. The 10 CFR 850 (view report; page 6931) contains further information on beryllium and beryllium-associated workers, and which organizations should have CBDPPs.

Through the 2019 calendar, the BAWR received data from the following 27 DOE-affiliated reporting organizations:

  • Ames Laboratory (AMES)
  • Argonne National Laboratory (ANL)
  • Brookhaven National Laboratory (BNL)
  • DOE Oak Ridge Office (DOE-ORO)
  • East Tennessee Technology Park (ETTP)
  • Fermi National Accelerator Laboratory (Fermi)
  • Golden SVCS, LLC (GSVCS)
  • Hanford Site (HAN)
  • Idaho National Laboratory (INL)
  • Kansas City National Security Campus (KCNSC)
  • Knolls Atomic Power Laboratory (KAPL)
  • Lawrence Berkeley National Laboratory (LBNL)
  • Lawrence Livermore National Laboratory (LLNL)
  • LLNL Clean Harbors Environmental Services (LLNL CHES)
  • LLNL NW (LLNL NW)
  • Los Alamos National Laboratory (LANL)
  • Nevada National Security Site (NNSS)
  • Oak Ridge National Laboratory (ORNL)
  • Pacific Northwest National Laboratory (PNNL)
  • Paducah Site (PADUCAH)
  • Pantex Plant (PTX)
  • Sandia National Laboratories (SNL)
  • Savannah River Site (SRS)
  • SLAC National Accelerator Laboratory (SLAC)
  • Y-12 Atkins Nuclear Secured (Y-12 ANS)
  • Y-12 National Security Complex (Y‑12)
  • Y-12 Navarro Research and Engineering (Y-12 NRE)

All 27 active reporting organizations collected health data through the operation of their medical surveillance programs.

Twenty-five (25) organizations conducted exposure sampling through their industrial hygiene programs. DOE Oak Ridge Operations (DOE-ORO) and Golden SVCS, LLC (GSVCS) do not submit exposure sampling data since their workers are in the BAWR due to prior work at another DOE site and have no potential for exposure.

There are 8 reporting organizations that previously participated in the program, but due to contract changes or work completion, no longer submit data. The previously submitted data from these organizations, referred to as inactive reporting organizations, remain in the BAWR.

The inactive reporting organizations are:

  • Advanced Mixed Waste Treatment Project (AMWTP)
  • LLNL Boston University (LLNL BU)
  • LLNL Envirocon, Inc. (LLNL ENVC)
  • National Strategic Protective Services, LLC for ETTP and ORNL (NSPS)
  • Rocky Flats Closure Project (RF)
  • Southwestern Power Administration (SWPA)
  • Wackenhut Security Services, Inc. for ETTP, ORNL, and Y-12 (WSI)
  • Y-12 URS Corporation (Y-12 URS)
  • Geographical Locations for 27 Active BAWR Reporting Organizations (2019)

  • Data Coordinator Changes by Reporting Organization (2013-2019)

    Data Coordinator Changes by Reporting Organization (2013-2019) infographic

    Each reporting organization designates a data coordinator who is responsible for coordinating activities at the site related to data collection, timely submittal of data, and responding to inquiries from the DOE Program Manager and ORISE Data Center as outlined in the DOE technical standard, DOE-STD-1187-2019. The following table shows that there were 12 data coordinator changes in 2018, which was higher than in any of the previous 5 years.

    Year No. (%) of Reporting Organizations Total Data Coordinator Changes Organizations with ≥2 Data Coordinator Changes in Same Year
    2013 5 (19%) 6 1
    2014 10 (37%) 15 5
    2015 6 (22%) 9 3
    2016 6 (22%) 7 1
    2017 5 (19%) 7 2
    2018 7 (27%) 9 2
    2019 11 (41%) 12 1

    Changes in data coordinators often result in the need for additional training and subsequent delays in data submissions. Therefore, significant data coordinator turnover can impact the timely acquisition of data and subsequent reporting of results.

  • Workers reported to the BAWR by Reporting Organization (2002-2019)*

    Workers reported to the BAWR by Reporting Organization (2002-2019)* infographic

    This figure shows the cumulative numbers of beryllium-associated workers reported to the BAWR by reporting organization. Through CY2019, there were 39,638 workers in the cumulative roster as compared to 37,805 workers in the cumulative roster through CY2018, for an increase of 1,853 workers. Hanford site has 16,562 employees in the roster, constituting the largest number (42%) in the cumulative roster.

    *Some reporting organizations have provided data that predate the 2002 start date of the Registry.

  • Gender and Age Distribution for Workers (2002-2019)*

    Gender and Age Distribution for Workers (2002-2019)* infographic

    Workers are predominantly male (approximately 88.4%) and greater than 50 years old (66.7%). This chart excludes 8 workers for whom demographic data were not available.

    *Some reporting organizations have provided data that predate the 2002 start date of the Registry.

Health Monitoring Results

Sites’ health clinics collect medical surveillance data on employees identified by their beryllium rosters. These data sets contain beryllium-related health monitoring information and the results of any specialized medical testing. The Site Occupational Medical Director (SOMD) determines the content and frequency of surveillance evaluations and tests based on policies, standards, and the employee’s health and work history. The most vital information collected and reported on an annual basis are the number of employees monitored for beryllium sensitization using the BeLPT, the number of new BeS cases identified, and the number of new cases of CBD. 

Some employees in the roster may decline testing for sensitizations. As a result, no records will be available for individuals who refuse this diagnostic evaluation. Some employees may have testing done independently (for example, as part of a former worker program), and in these cases results may be unavailable for Registry reporting unless the employee releases their evaluation report, and it becomes part of the organization’s electronic medical records. Also, advanced medical testing results when employees are referred (after findings suggestive of possible CBD) to a pulmonary medicine or other specialized clinic for follow-up diagnosis and care may not be reported and/or can be difficult to collect.

Sensitization and CBD Screening

The cumulative number of workers with BeLPT screening results submitted to the BAWR through CY2019 was 27,204. When compared with the 25,957 workers screened through CY2018, this corresponds to an additional 1,247 employees tested for an increase of 5%.

There was a total of 532 sensitized workers included in the BAWR, and medical staff diagnosed 155 as having CBD through CY2019. BeS and CBD are mutually exclusive categories, i.e., if a person who is BeS receives a CBD diagnosis, the person’s diagnosis moves to the CBD category and is no longer counted in the BeS category.

    The total number of beryllium-sensitized employees increased by 17 through CY2019 (523 total BeS cases reported through CY2018). The newly reported BeS cases were from 6 reporting organizations (1 at GSVCS, 4 at HAN, 9 at LANL, 1 at LLNL, 1 at PADUCAH, and 1 at Y-12). Ten (10) employees had reported dates of sensitization in 2019. The remaining seven (7) cases (from GSVCS, LANL, and PADUCAH) had dates of sensitization ranging from 2009 through 2018. Seven (7) prior BeS cases from LANL (5), NNSS (1), and SNL (1) progressed to CBD in CY2019, hence, the total CBD cases increased by 7.

    Twenty (20) of the reporting organizations have beryllium-sensitized employees and 11 have employees who have been diagnosed with CBD.

    Number of Workers Undergoing BeLPT and Diagnosed with BeS or Diagnosed with CDB (n=39,638) (2002-2019)* infographic

    This table provides the numbers of beryllium-associated workers with BeLPT test results submitted to the BAWR each year, and the year of first positive or abnormal BeLPT result for those who were beryllium-sensitized or diagnosed as having CBD. First positive or abnormal BeLPT result is an important medical surveillance sentinel, resulting in earlier or more frequent repeat testing, hence, earlier diagnosis, earlier work restrictions, and more successful treatment. It is also a criterion for eligibility for compensation and payment of medical expenses under the Energy Employees Occupational Illness Compensation Program Act (EEOICPA). Two (2) abnormal BeLPT results or 1 abnormal and 2 borderline BeLPT results are required to categorize an employee as BeS. Since a worker may choose not to have repeat BeLPT measurements, may change work and have long lags between measurements, or may not test abnormal for a period of time, the year of first BeLPT provides a more reliable metric than the year a worker becomes BeS.

    The yearly average for workers developing sensitization, whose first abnormal lymphocyte proliferation test results were between 2000 and 2009, was 34. This rate dropped to an average of 13 from 2010 to 2019. For workers later diagnosed with CBD, the yearly averages dropped from 9 to less than 1 per year for the respective time frames. These results provide evidence that programs are serving to improve worker protection and reduce the risk of CBD.

    This table lists beryllium-sensitized, or CBD diagnosed workers, through 2019 grouped by their work history activity, which is a high-level rollup of job function. Based on the data submitted through 2019 and as presented in the table, the majority of both reported beryllium sensitizations (36.9 %) and CBD cases (39.9%) occurred among the broad occupational groups of Crafts and Line Operators.

    This figure compares the percent of BeLPT tests conducted to the number of employees tested for each reporting organization in 2018. Employees may be BeLPT tested multiple times in a year if they have abnormal or borderline results. Therefore, the number of BeLPT tests conducted are higher than the number of employees tested.

Exposure Monitoring Results

The BAWR receives beryllium work history and exposure data. The submission contains information about all activities with the potential for beryllium exposure including where the beryllium-associated worker currently works or previously worked, and the exposures associated with those activities. Reporting organization staff collect retrospective work history information through questionnaires and interviews with the worker or from records if accessible. This information includes location, organization, and job title for employees who work directly with beryllium, work in areas of potential beryllium exposure even if not working directly with beryllium, and activities with potential casual exposure to beryllium, such as working near an area where others are working directly with beryllium.

Exposure Monitoring Trends - Employees

The cumulative number of employees monitored through CY2019 was 7,239 compared to 6,917 employees monitored through CY2018 as reported in the Beryllium-Associated Worker Registry 2018 Dashboard. This equates to an increase of 322 employees monitored for exposure to beryllium through CY2019. The increase in the CY2019 report is higher than the reported increase of 256 between CY2017 and CY2018 and higher than the increase of 220 employees between the CY2016 and CY2017 reports.

Seventeen (17) reporting organizations provided exposure monitoring results with monitoring dates in 2019. Organization-specific totals for a given year may change from totals in previous annual reports due to late reporting and/or corrections.

    Number and Percent Proportion of Exposure Sample Results by Year (N=60,223) (2010-2019). infographic

    The numbers of exposure sampling results in the Registry by year monitored for each of the past 10 years are shown in the line chart.

    As can be seen, the numbers have steadily declined in recent years. The reporting organizations that collected and submitted exposure monitoring sample data show a downward trend which, in some cases, impact the analysis and interpretation of results in the BAWR. The small sample size reduces accuracy and causes higher variability in the statistical models used for the BAWR analyses.

  • Comparison of the Number and Percent Proportion of Exposure Samples to Workers with Exposure Sampling Results by Reporting Organizations (n=2,593) (2002-2019)

    Comparison of the Number and Percent Proportion of Exposure Samples to Workers with Exposure Sampling Results by Reporting Organizations (n=2,593) (2002-2019) infographic

    This graphic illustrates the distribution of exposure samples and employees monitored across 17 reporting organizations during 2019. Similar to the beryllium screening results, most employees monitored for beryllium exposure have multiple exposure measurements throughout the year. The frequency of monitoring is dependent on the employee’s specific type of work and their employer’s monitoring schemes.

    Reporting organizations submitted a total of 110,905 exposure measurements to the Registry through CY2019. This equates to an additional 3,048 exposure sampling results collected and submitted to the 107,857 total through CY2018. The number of monitoring results for CY2019 alone was 2,593 as indicated above. Therefore, 455 of the sampling results submitted in CY2019 were sampling data for years prior to 2019.

  • Number and Percent Proportion of Non-Detectable Results Exposure Measurements, Detectable Exposure Measurement Results and Exposure Measurement Status Not Reported (N=110,905) (2002-2019)*

    Number and Percent Proportion of Non-Detectable Results Exposure Measurements, Detectable Exposure Measurement Results and Exposure Measurement Status Not Reported (N=110,905) (2002-2019)* infographic

    Of the 110,905 exposure monitoring records submitted to the Registry through CY2019, 90.7% have “non-detectable” results, indicating that the sample analysis results were less than the laboratory’s reporting limit. The reporting limit can vary from sample to sample because of differing flow rates of the sampling equipment used and because of the presence of other materials on the sample that can interfere with the analysis. Reporting limits typically vary from 0.01 to 0.05 µg/m3, which is one-twentieth to one-quarter of the action level of 0.2 µg/m3.

    In comparison, 107,857 cumulative exposure monitoring results were submitted through CY2018, for an increase through 2019 of 3,048 records (with monitoring dates in 2019 and earlier). This 3,048 increase in sampling results is lower than the 3,104 increase in records submitted between 2017 and 2018 and even lower than the 3,584 increase between 2016 and 2017.

    *Some reporting organizations have provided data that predate the 2002 start date of the registry.

    **Non-detectable indicates that analysis results were reported as less than the laboratory's reporting limit.

    *Many individuals were monitored in more than 1 year. The total number of individuals measured at least once in the 10-year period from 2010 through 2019 is 4,103.

    The detailed data presented in the table above provide additional summary statistics for the DOE-wide 8-hour TWA results for each of the past 10 years. The very high percentage of non-detected results from workplaces compliant with the 0.2 µg/maction level points to the need to develop more sensitive exposure monitoring methods to support estimates of individuals’ actual exposure levels.

    These statistical methods accommodate the high percentage of non-detect results (left censored) in these data sets. These analyses exclude non-detected values greater than 0.2 µg/m3. For details, see “Statistical Methods and Software for the Analysis of Occupational Exposure Data with Non-Detectable Values” Frome EL and Wambach PF, ORNL/TM-2005/52.

    Totals for an individual year may vary from previous reports due to late reporting and/or corrections. The data reported in the BAWR indicate that the CBD prevention programs operated at DOE sites have continued to maintain a high level of compliance with the 10 CFR 850 action level of 0.2 µg/m3 over the past 10 years.

The detailed data through 2019 presented in the accompanying table include the summary statistics for cumulative 8-hour TWA monitoring results by craft job title. Laborers, machinists, electricians, millwrights, plumbers and fitters, iron workers, carpenters, hazardous waste workers, painters, mechanics, waste-management mechanics, sheet metal workers, and HVAC mechanics individually have percent exceedances that are higher than when all crafts are combined (0.7% to 6.8% as compared to 0.6%, as shown in the table below).

    Among craft workers, HVAC mechanics and sheet metal workers show percentages exceeding the 0.2 µg/m3 action level that are higher than the percentages experienced by other craft workers. However, the percentage for HVAC mechanics reflects exposure monitoring results for only 29 individuals, and for sheet metal workers only 67 individuals.

    Percent of 8-hour time weighted average (TWA) Exceeding Action Level 0.2 µg/m&lt;sup&gt;3&lt;/sup&gt; by Reporting Organization (2002-2019)* infographic

    Percent exceeding 0.2 μg/m 3 based on 95% Confidence Limits

    This chart summarizes the cumulative 8-hour TWA exposure monitoring results through 2018 by reporting organization. The detailed data presented below include the summary statistics for the cumulative 8-hour TWA monitoring results for each reporting organization. The percent of monitoring results exceeding the action level at Fermi (not included in the graphic above due to the very large value, 17.2%, exceeding the scale for the figure), Y-12 NRE, Y-12, SNL, ANL, and PTX (ranging from 1.4 to 4.6%) were higher than the overall percent exceedances when data across all organizations are combined (1.3%).

    The graphic does not include results from AMES, BNL, Fermi, LBNL, LLNL CHES, and SLAC because of the small number of total samples and/or low percent exceeding the action level. Collectively, these data indicate that the majority of reporting organizations have acceptable sampling programs. However, the data also show that some organizations with ongoing beryllium activities, but small numbers of exposure monitoring samples could revisit their sampling strategies and consider increasing the volume of sampling.

  • Exposure Monitoring Results Exceeding Action Level 0.2 µg/m3 by Reporting Organization (2019)*

    Exposure Monitoring Results Exceeding Action Level 0.2 µg/m&lt;sup&gt;3&lt;/sup&gt; by Reporting Organization (2019)* infographic

    Percent exceeding 0.2 μg/m3 based on 95% Confidence Limits

    This graphic provides the percent of exposure monitoring results that exceeded the action level by reporting organization for CY2019. The upper confidence limit is above 5% at organizations that reported 62 or fewer sampling results in 2019 or reported similar time weighted average values for detects and non-detects. Fewer organizations reported exposure monitoring in recent years, and those organizations submitting data have also reported fewer sampling results. This downward trend impacts the analysis and interpretation of results in the BAWR. The small sample size reduces accuracy and causes higher variability in the statistical models used. Certainly, the wide confidence intervals in the single year 2019 analysis demonstrate the reduction of statistical power and confidence in the interpretation when compared to similar but larger samples of the population.

    Historically, this graph excluded results for reporting organizations with small numbers of total samples. This figure instead includes data for all 17 organizations since all but 5 organizations reported 62 or fewer results for CY2019.

    The table below gives additional summary statistics for organizations reporting exposure data to the BAWR during 2019. Organizations that did not report data for calendar year 2019 are not included in this table.

    The data in the graphic and table show that Sandia National Laboratory had the greatest percentage (23.7%) of reported exposure monitoring results exceeding the action level in CY2019.

    This table provides the reporting organization, process description, 8-hour TWA, and the respirator assigned protection factor (APF) for the results observed above the action level through 2019.

    Exceedances for 2019 were less than in 2018 with twenty-one (21) samples exceeding the action level in 2019, compared with 31 in 2018, and 36 in 2017. Since the total reported exposure sampling results continue to decrease over time, the proportion of exceedances is greater than in previous years. In all cases work planning processes identified the potential for beryllium exposure and workers wore appropriate respiratory protection.

  • Exposure Monitoring Results Exceeding Action Level 0.2 µg/m3 by Reporting Organization (2018)

    Exposure Monitoring Results Exceeding Action Level 0.2 µg/m&lt;sup&gt;3&lt;/sup&gt; by Reporting Organization (2018) infographic

    This table provides the reporting organization, process description, 8-hour TWA, and the respirator assigned protection factor (APF) for the results observed above the action level through 2018.

    Exceedances for 2018 were less than in 2017, but greater than in any other years since 2012. Thirty-one (31) samples exceeded the action level in 2018, compared with 36 in 2017, and 26 in 2016. Since the total reported exposure sampling results continue to decrease over time, the proportion of exceedances is greater than in previous years. Exceedances in 2018 were associated with RCRA and fire equipment maintenance at INL and support, and production activities at Y-12. In all but a few cases, work planning processes identified the potential for beryllium exposure and workers wore appropriate respiratory protection.

Health and Monitoring Comparisons

Two different reporting organization groups collect the data associated with health monitoring and exposure monitoring. Occupational health and medical groups collect health monitoring data and industrial hygiene groups collect exposure monitoring data. In most cases, a data coordinator collates the data prior to submission to the Registry. In this section, the health screening data compared to the exposure monitoring data provides insight on the effectiveness of coordination between the 2 activities.

  • Comparison of the Number and Percent Proportion for Beryllium-Associated Workers Diagnosed with BeS or CBD with and without Exposure Sampling Results by Reporting Organizations (n=687) (2002-2019)*

    Comparison of the Number and Percent Proportion for Beryllium-Associated Workers Diagnosed with BeS or CBD with and without Exposure Sampling Results by Reporting Organizations (n=687) (2002-2019)* infographic

    The data in the figure shows the collective number of BeS or CBD individuals through 2019 who have had exposure monitoring results submitted to the Registry. The figure also illustrates the collective number of individuals who have not had exposure data submitted to the Registry. More than two- thirds (465 out of 687, or 68%) of the workers currently identified as BeS or diagnosed with CBD have no exposure sampling data. The proportion reported in the 2018 and 2017 annual summaries were also 68%. The proportion reported in each of the summaries for 2016 through 2013 was 67%.

    DOE and ORISE program staff evaluated these data by each mutually exclusive subcategory, BeS or CBD. Of the 532 employees who are sensitized (BeS) and have not progressed to CBD, only 172 (32%) had any exposure sampling measurements submitted to the Registry. Only 109 (21%) of these sensitization cases had any exposure records dated earlier than their reported date of sensitization.

    Of the 172 sensitization cases with exposure sampling data, 63 cases only had exposure sampling data with monitoring dates later than their reported date of beryllium sensitization. In other words, 37% of the BeS cases with exposure data had exposure monitoring initiated only after diagnosed as sensitized.

    Eighty-eight (88) of the 532 sensitization cases had at least one reported exposure record dated later than their reported date of beryllium sensitization; but this includes the 25 cases that had exposure data both before and after their date of sensitization.

    Of the 155 employees reported as diagnosed with CBD, 50 (32%) of the cases had at least one exposure sampling measurement submitted to the Registry. Only 31 (20%) of the total CBD cases had at least one reported exposure record in the Registry dated earlier than their reported date of CBD diagnosis.

    In comparison, 31 (21%) CBD cases had at least one reported exposure record dated later than their date of CBD diagnosis. Industrial hygiene programs monitor workers diagnosed with CBD to ensure compliance with restricted duty. Nevertheless, 19 of the CBD cases only had exposure sampling data later than their reported date of CBD diagnosis. Therefore, only 29 of the CBD cases had exposure monitoring records prior to their CBD diagnosis. Most sites will not assign BeS or CBD workers to jobs where there is a risk of beryllium exposure, so no sampling is required.

  • Comparison of the Percent of Workers Diagnosed with BeS or CBD with Percent Exceeding Action Level 0.2 μg/m3 by Reporting Organization (2002-2019).

    Comparison of the Percent of Workers Diagnosed with BeS or CBD with Percent Exceeding Action Level 0.2 μg/m3 by Reporting Organization (2002-2019). infographic

    The figure compares the cumulative percent of workers sensitized or CBD to the percent of exposure samples exceeding the 0.2 µg/m3 action level for each reporting agency. These data illustrate that no statistical correlation exists between the incidence of BeS/CBD and the percent of exceedances among the exposure sampling results submitted to the Registry (Pearson product moment correlation coefficient = -0.077). The lack of correlation could be due to sensitization and CBD cases associated with past work locations or conditions rather than the environment currently monitored. However, it is also possible that the exposure monitoring programs are missing sources of exposure. Reporting organizations with low exposure monitoring results and high sensitization or CBD rates should investigate cases to determine if there is a possibility of ongoing exposures.
